[Question #4296] About condoms...

I am sure I am overthinking this. 

I recently had condom protected oral and vaginal sex with an escort. I believe the condom was latex, she said she got it from the clinic so I cannot see them giving out lambskin. As far as I know the condom was intact. No obvious explosion or tear. 
My questions are

1. Since the statistic is 1 per 1000/2000 exposures would cause hiv without a condom than wouldn't it be drastically lower even if I didn't have a latex condom?

2. I have been in this std/I fear for a few months now since I had an exposure a few months back (as seen in my previous posts) should I test after this incident?

3. When if ever is it necessary to use a PCR test instead of a 4th generation test? 

4. Do PCR tests have a higher false positive rate?

Thank you for your time.

Welcome back, but sorry you found it necessary. Directly to your questions:

1) Yes, the risk of HIV is far lower with a condom than without. Isn't that obvious? Probably at least a hundred fold lower.  But the risk of HIV at the time of your exposure is irrelevant, since testing has shown that you weren't infected, regardless of the risk at the time.

2) Your previous exposure and its risks were discussed in detail in your previous threads. I suggest you re-read them. The main point is that the antigen-antibody (4th generation) blood tests are 100% conclusive any time 6 weeks or more after the last possible exposure. Therefore, such results overrule all other considerations:  no matter how high (or low) the risk of HIV at the time of exposure, and regardless of even the most typical symptoms of a new HIV infection, the test result rules.

3) The main purpose for PCR is in people at very high risk, often with symptoms, sooner than 2-3 weeks after exposure. Once 6+ weeks have passed and an AgAb test is negative, PCR is never needed.

4) PCR used to have a small false positive rate, but with current test technologies, it almost never happens.

Time to move on. This will have to be your last question on this forum about your recent exposure and worries about HIV.

No I'm sorry. This was a new sexual encounter.  Literally 2 nights ago. I know I have a problem. I will be seeing a counselor soon for my issues. 
I had previously asked the PCR question but did not get an answer on it directly.  Thank you for that. 
My question was in term of latex vs other condom material vs no condom at all.

I just wanted your expert advice on if I have to worry after this last exposure. I will try my best to make it my last extramarital affair, it has really affected me on many levels. Thank you very much for your time.

Also the reason I asked about the PCR test is because on the medhelp forum whenever someone asked about autoimmune conditions (mine is hypothyroidism) they usually got the PCR test alongside the ag/ab test and where told that the autoimmune condition didn't matter because the PCR test doesn't look for antibodies. So I read that basically to say that ag/ab test is good but that the PCR is better for those people. 

You did tell me that it doesn't matter because I tested after 42 weeks and beyond with the ag/ab.  I don't know how autoimmune diseases affect antibody production. I do understand that the antigen would be present though. Right? I just wanted to be clear on that. That is all. I know you see it as I'm being overly anxious. Again thank you.

I didn't understand this is about a new exposure. However, we really can't help judge any particular exposure. I can reaffirm what you already probably know:  since you used a condom for both vaginal and oral sex, there was no HIV/STD risk and you do not need testing.

All the business you can find online about autoimmune diseases (and many other medical conditions) and HIV antibody production are meaningless in the era of antigen-antibody testing. None of these conditions actually is likely to interfere with antibody production. But if it did, the antigen component of the test would still work normally. There are NO known medical conditions or medications that have any effect at all on the modern AgAb HIV tests. None, not a worry, forget it -- period.

Thank you Dr. Handsfield for the help. I have read that last paragraph quite a few times. I have had a hard time with this and I know I have tested quite a bit. 

Is it possible my anxiety can be causing my symptoms? I have had throat issues and pain in my feet for a while now. I've lost quite a bit of muscle also. 

Can the early stage like the first few weeks of infection affect a women's menstrual cycle? Like 8 days when it's usually 5? 

How certain is the 6 week ag/ab negative? I have read you say 100%. I am not questioning you,  I just know that saying something is 100% is pretty strong assurance. 

I should be starting counseling soon to deal with this.  I do appreciate your knowledge and this forum. 

Again thank you.

Anxiety is a good bet for such symptoms. And whenever someone suggests his or her own symptoms have a psychological origin, usually s/he is correct.

Neither HIV nor other STDs would have any effect on a woman's menstrual cycle.

100% confidence in negative AgAb tests at 6 weeks is the expert consensus.

Don't overthink all this. As I may have said in your previous thread(s), in the 14 years I have been doing this and my previous forum at MedHelp.org, with thousands of questions about HIV risk, not one person who asked about HIV risks from an exposure that worried them ever later posted that they had caught HIV. Not one. You won't be the first. If and when that happens, almost certainly it will be from a real risk (like unprotected sex between men, or sex with a known HIV infected person), and not a minimal risk exposure like a condom protected heterosexual exposure like yours.

Having said all that, the old folk phrase come to mind:  If you can't stand the heat, get out of the kitchen. You obviously make repeated sexual choices that you regret and then worry about them despite having only safe sex. You either need to simply not have sex outside your marriage; or do your best to minimize the risk, as you have been doing, and learn to move on afterward without worry. I agree that counseling probably is the best way to achieve either of these goals.

That concludes this thread. It should be your last one about such exposures and your HIV/STD worries from them. I do hope the discussions have bene helpful.
